IMPROVEMENT IN LANDING-WHEELS FOR KNITTING-MACHINES.

Specification forming part of Letters Patent No. 168,983, datedOctober19, 1875; application filed April 28, 1875.

To all whom it may concern Be it known that I, ROBERT W. GORMLY, of thecity of Troy, in. the county of Rensselaer and State of New York, haveinvented an Improved Landing Wheel for Knitting- Machines, of which thefollowing is a specification:

My invention relates to certain new and useful improvements in landingor cast-off wheels for knitting-machines, the object of which is, afterthe loop is formed by the burrwheel or looper in common use, to have adevice which, in its operating parts, is rendered more durable in use,and more readily and firmly adjustable, than devices ordinarily employedfor the same purpose, which construction and arrangement will be fullyunderstood from the following description, reference being had to theaccompanying drawing, forming part of this specification.

Figure l is a plan of the landing-wheel. Fig. 2 is a vertical section ofthe same. Fig. 3 is a perspective of the inner slotted plate of thesame. Fig. 4 is a detached view of one of the blades. Fig. 5 is a viewwith cap screw or nut removed, showing the upper edge of the blades inposition. Fig. 6 is a perspective of the larger supporting-plate of mydevice. Fig. 7 is a perspective of my improved landing or cast-off wheelon the spindle at the proper angle to operate in connection with aknitting-machine.

Similar letters of reference indicate corresponding parts.

In the case here presented, A represents a top view of the spindle; B,Fig. 2, the bushin g, upon which rests the shoulder of the lower plate0, the upper end of the bushing having a screw-thread to hold thecap-piece, E, Fig. 2, firmly. The circular V-channel in the lower plateG, in which the nib of the blades rests, is seen at 1 and 2, Fig 2, andin Fig. 5. D is the middle plate; F, the blade.

In landing or cast-off wheels, as ordinarily constructed, the bushing isdriven into the hub of the wheel, and, after the slots are cut into theouter rim, the blades are soldered in in position. Whenever the bushingis worn out, or the blades become unserviceable, great delay isoccasioned, and injury is liable to result to the wheel from withdrawingand replacing these parts. Again, in the ordinary constructionuntempered steel blades of soft steel, in rectangular or irregularforms, are soldered into the slotted partitions ofthe rim, and they arethen filed down to the required shape to give the proper diameter to thewheel.

7 On the contrary, all the operating parts of my improved landing-wheelare separately and nicely adjusted as to form and finish, and properlytempered before being put together. The blades are cut out ofsheet-steel in the required form, and are then thoroughly tempered andtumbled ready for insertion, and rendered most efiicient and durable inuse.

The bushing of the wheel can be readily removed when wear or breakagemay require. The blades, though detachable, are firmly inserted-andsecurely held in the V-channel and slots. The cap-piece E, Fig. 2, isscrewed on the upper end of the bushingB, so as to rest firmly upon theupper edge of the blades, and just within the rim of the lower plate.

The cap-piece E may be readily unscrewed, the blades removed from theirposition and new ones inserted, and, in fact, all the separate parts ofmy device being made in similar sets, properly tempered and finished,any part may readily be removed and replaced by an unskilled workman orthe ordinary mill-operative, and no unnecessary delay intervene; and byreason of these parts being constructed and arranged in such form andmanner as to be easily detachable and firmly adjusted, the operatingparts can be better titted for more eificient use, and be more durable,than the ordinary landing-wheel.

I construct and arrange my improved landing or cast-off wheelsubstantially as follows: I make the head of the bushing B, Fig. 2, withtwo flattened sides, to enable it to be surely grasped and turned, andthe smaller end with a screw-thread to engage with the head of thecap-piece E. The plate 0 has a shoulder, (seen at 2,) which rests uponthe head of the bushing, and a slotted rim, extending in width justabove the blades, the slots being cut at an angle of about thirtyfivedegrees. Upon the plate 0, and around the bushing, is placed the centerplate D, Fig. I

3, whose outer periphery is cut with slots corresponding with those inthe rim. Just within the rim of the larger plate I cut or groove aV-channel, to correspond with the nib projections on the blades. Theblades F are inserted spective wheels, although having their operativeparts similarly constructed and arranged, from their diflerent sizesandpositions on knitting-machines, perform difierent purposes or functions.

What I claim, and desire to secure by Letters Patent, is-

The combination of the bushingB and blades F with the slotted detachableplates 0 and D and cappiece, constructed substantially as and for thepurpose set forth.
